  • Patent number: 8993704
    Abstract: In a process for producing an elongated polyethylene component, such as a fiber or membrane, polyethylene powder having a molecular weight of at least 3×105 g/mol as determined by ASTM 4020 is dissolved in a solvent to produce an extrudable solution. The solution is then extruded through a die to form an elongated component and at least part of said solvent is removed from the elongated component. The polyethylene powder used in the process is produced by polymerizing ethylene in the presence of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand.

  • Patent number: 8960723
    Abstract: A quick-release closure for a vehicle-mounted end of a seat belt in a motor vehicle having a fitting part, and a vehicle-mounted attachment part. A first opening is provided in the fitting part, in which one end of the seat belt can be attached by means of a loop which is guided through the first opening. A second opening is provided, in which the attachment part can be locked to a locking head. In the second opening a spring element is provided that can be moved from a mounting position) into a locking position. The locking head of the attachment part can be inserted into the opening in which the spring element is arranged in the mounting position, and the spring element can be moved into the locking position by a relative movement of the locking head with respect to the fitting part, securing the locking head in position.
